CSM3637P

Ultra High Precision, Surface Mount 4-Terminal Precision Resistor with

Increased Power to 5W (40A max), Resistance Values from

3 mto 100 m, and TCR to ± 15 ppm/°C

FEATURES

 Resistance range: 3 m to 100 m

 Temperature coefficient of resistance (TCR):

3 mto 100m : 15 ppm/°C maximum

 Load life stability: ± 0.2 % (70 °C, 2000 h at rated

power)

INTRODUCTION

The CSM3637P is a low value current sense resistor,

providing power and precision in a four terminal, surface

 Power rating: to 5 W (see Table 1)

 Resistance tolerance: to ± 0.1 %

mount configuration. Its all welded construction is made up

of a Bulk Metal^®resistive element with plated copper

terminations.

 Vishay Foil Resistors (VFR) are not restricted to standard

values; specific “as required” values can be supplied at no

extra cost or delivery (e.g. 10.2345 m vs. 10 m)

There are many current sense resistors on the market. Until

now the combination of very stable and precise resistors

with low TCR of ± 15 ppm/°C maximum, tight tolerance of

± 0.1 % and load life stability of ± 0.2 % (2000 h, + 70 °C at

rated power) was not easily available.

 Short time overload: ± 0.2 % typical

 Proprietary processing technique produces extremely low

resistance values with improved stability

 All welded construction

 Solderable terminations

The key performance of the new CSM3637P is its high rated

power up to 5W. This option became available due to a

special design which consists of a heat sink on the top of the

resistive element, thus allowing a better heat dissipation.

 Very low inductance 0.5 nH

 Excellent frequency response to 50 MHz

 Low thermal EMF < 3 µV/°C (DC offset error, significant for

low values)

These specifications are based on tests performed in

accordance with methods prescribed by appropriate

MIL-PRF standards (MIL-PRF-55342 and MIL-PRF-49465).

 Maximum current: up to 40 A

 Four terminal (Kelvin) design: allows for precise and

The four terminal device separates the current leads from

the voltage sensing leads. This configuration eliminates the

effect of the lead wire resistance from points A to B and

C to D.

accurate measurements

 Terminal finishes available: lead (Pb)-free, tin/lead alloy

 Prototype quantities available in just 5 working days

or sooner. For more information, please contact

foil@vpgsensors.com

In addition, a key feature of the CSM3637P is its low thermal

EMF design (very important for low ohmic value DC

applications). The welded terminals make intimate contact

with the chip thereby minimizing temperature differentials.
